Abstract: A method for antenna switching is described. The method includes transmitting using a first antenna. The method also includes determining that a trigger occurs to switch to transmitting using a second antenna. The trigger is based on a combination of a physical uplink shared channel (PUSCH) maximum transmit power level (MTPL) counter and a physical uplink control channel (PUCCH) MTPL counter. The method further includes switching to transmitting using the second antenna based on the determination.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE beam selection based on service demands are disclosed herein. An example method of wireless communication includes determining to select an UL beam having a higher EIRP capability than an EIRP capability associated with a current beam for transmitting on UL when at least one of a target transmit power based on a TPC exceeds an EIRP capability associated with the current beam or when an amount of data in a buffer of the UE is greater than a data threshold. The example method also includes determining, upon determining to select the UL beam, a set of UL beams with an EIRP capability satisfying an EIRP capability threshold and a respective beamforming direction corresponding to a beamforming direction associated with the current beam, selecting one UL beam of the set of UL beams, and transmitting on UL on the selected UL beam.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.
